An intelligent bionic dressing (IBD) for simulating amniotic cavity includes an outer layer, an interlayer, an inner layer, a monitoring unit, a filling unit, a heating unit, a control unit, a waste liquid collection unit, and a plurality of accessories, configured to form a simulated amniotic cavity environment on a wound. Artificial amniotic fluid and its additives can circulate in the simulated amniotic cavity. The IBD provides a warm, moist, slightly acidic, sterile, pressureless and air isolated repair microenvironment for the wound, so as to monitor the wound in real-time, reduce dressing changes, rapid repair the wound, and reduce a scar.

Provided herein are microbial infection indicator devices, including dressing with indicators, standalone indicator inserts or disks that can be freely placed at a wound site or dressing, and applications thereof for displaying a visible or detectable signal to a user upon detection of an analyte or biomarker indicative of an infection, such as a color change.

A wireless system comprising a first wireless device and a second wireless device. The first wireless device is configured to operate with less than 15 milliamperes of current. The second wireless device has an internal power source and is configured to transmit one or more radio frequency signals to the first wireless device. The first wireless device is configured to receive the one or more radio frequency signals from the second wireless device. The first wireless device is configured to harvest energy from the one or more radio frequency signals. The first wireless device is enabled for operation after a predetermined amount of energy is harvested from the one or more radio frequency signals. A communication handshake occurs between the first and second wireless devices to indicate that the first wireless device is in communication with the second wireless device. The first wireless device is configured to perform at least one task from harvested energy.

A modular kinesiology or physio tape adapted to produce heating or cooling. The tape includes a layer of material having a chamber for retention and release of a removable packet of cooling or heating material and a mechanism for securing the layer directly onto skin of a user. The removable packet of cooling or heating material has dimensions optimized for manual insertion into and removal from the chamber. Preferably, the material is flexible and includes an adhesive for securing the layer to the skin. The material has a first surface for contacting skin, a second surface parallel to the first surface for receiving and retaining the removable packet and an edge between the first and second surfaces. In one embodiment, multiple slits are provided in the second surface having dimensions adapted to receive and retain said packet. In yet another embodiment, a heating packet is implemented with a button/coin type battery circuit with an optional mechanism for controlling the generation of heat thereby.

A dressing assembly for providing a warning to a patient or caregiver that the patient needs attention. The dressing assembly is adapted to be applied to or near a surface of the patient's body and generate electrical outputs corresponding to soft tissue pressure and other health characteristics sensed at the surface. The dressing assembly includes a pocket formed therein for removable, secured and protected insertion of a variety of different sensors such as multiple pressure sensors.

A sensing chip attached to a bandage monitors the healing process of a wound by detecting growth factors, thrombin and fibrinogen. The complementary metal-oxide semiconductor includes a functionalized working electrode, functionalized counter electrode and functionalized reference electrode. The healing progress is stimulated by generating oxygen in the wound.

Wound therapy dressings are provided. The wound therapy dressings may include at least one selectively transparent layer with a refractive index in a range wherein interaction between the selectively transparent layer and fluids from a treatment site switches the selectively transparent layer from a first, opaque state to a second, transparent state. Dressings that include multiple layers may include polymer films with a plurality of fluid restrictions, a manifold, a transparent polymer drape, and a hydrophobic polymer layer. The dressings may further include negative pressure therapy treatment input devices. A method of use wherein the dressings are used to monitor fluid flow, exudate, and maceration around a treatment site is also provided.

Concentrating devices, systems, and methods include those for separating fluids to be sensed (e.g., analytes, such as volatile organic compounds (VOCs) and/or other chemical substances) from other fluid (e.g., a carrier gas, air, etc.) of a fluid mixture received from a target area of a subject's anatomy (e.g., a subject's skin, a wound on a subject, etc.). In some cases, the concentration system may include a housing and a rotor positioned in a compartment of the housing. The housing may receive a fluid mixture in the compartment and rotation of the rotor relative to the housing may separate fluid to be sensed in the fluid mixture from other fluid of the fluid mixture.

A wound therapy system includes an instillation fluid canister configured to contain an instillation fluid, a pump fluidly coupled to the instillation fluid canister and operable to deliver the instillation fluid from the instillation fluid canister to a wound, a user interface configured to receive user input indicating one or more geometric attributes of the wound, and a controller electronically coupled to the pump and the user interface. The controller is configured to determine a volume of the wound based on the user input, determine a volume of the instillation fluid to deliver to the wound based on the volume of the wound, and operate the pump to deliver the determined volume of the instillation fluid to the wound.

An antenna assembly includes: a wearable antenna including a conductive signal layer having a radiating surface; a feed conductive layer; and an insulating layer in between the conductive signal layer and the feed conductive layer, and wherein the conductive signal layer, the feed conductive layer, and the insulating layer are fabric-based, wherein the wearable antenna is shaped and sized to be embedded in a subject's clothing with sufficient flexibility to be stretched and bent as the subject implanted with a passive implantable stimulator device maintains routine daily activities, and wherein the wearable antenna is electrically tuned and configured to have the radiating surface of the conductive signal layer facing the subject's skin and a feed point of the feed conductive layer connecting to a controller such that the wearable antenna is non-inductively coupled to the implanted passive stimulator device to supply power the passive implantable stimulator device wirelessly and non-inductively.
